[PATCH] USB: fix in usb_calc_bus_time
This patch does the same swap, i.e. use the ISO macro if (isoc). Additionally, it fixes the return value - the usb_calc_bus_time function returns the time in nanoseconds (I didn't notice that before) while the HS_USECS and HS_USECS_ISO are microseconds. This fixes the function to return nanoseconds always, and adjusts ehci-q.c (the only high-speed caller of the function) to wrap the call in NS_TO_US().
